Fasting blood glucose 6.2mmol/L can be lowered by dietary control and appropriate exercise; two-hour postprandial blood glucose 6.2mmol/L does not require glucose-lowering measures. The normal range of fasting blood glucose is 3.9~6.1mmol/L, so fasting blood glucose 6.2mmol/L is slightly higher, belonging to impaired fasting blood glucose. Fasting blood glucose 6.2mmol/L can be controlled by diet, such as formulating the total calories that should be consumed per day according to the patient’s weight, height, activity level, etc. Avoiding high-sugar, high-fat foods, such as fatty meats, deep-fried foods, cakes, milk tea, etc., as well as actively engaging in aerobic exercise, such as jogging, jumping rope, etc., can help to lower blood glucose. The normal value of two-hour postprandial blood glucose should be less than 7.8mmol/L, so two-hour postprandial blood glucose of 6.2mmol/L is within the normal range and does not need to take glucose-lowering measures. It is recommended to go to the hospital when abnormal blood glucose value occurs.
